SHOULDER BIOMECHANICS | INTRODUCTION & STERNOCLAVICULAR JOINT ANATOMY

Detailed biomechanical discussion of shoulder complex in a series of videos. This series on biomechanics discuss all four joint of shoulder complex namely STERNOCLAVICULAR JOINT, ACROMIOCLAVICULAR JOINT, GLENOHUMERAL JOINT AND SCAPULOTHORAIC JOINT. This First video on series discuss the Introduction to shoulder complex and then discuss STERNOCLAVICULAR JOINT.
The Sternoclavicular joint is discussed in detail with emphasis on Type of joint, Degrees of freedom, Atricular surfaces, Accessory structres, ligaments and Motions of sternoclavicular joint.The sternoclavicular disc is a very important accessory structure in sternoclavicular joint along with joint capsule,and three ligaments namely STERNOCLAVICULAR,COSTOCLAVICULAR AND INTERCLAVICULAR. Role and function of all ligaments as well as disc is seen in detail.
